1.Heat a casserole over medium heat, add lard and speck, cook until fat renders (3-5 minutes), add onion and stir occasionally until tender (10-15 minutes). Add potato, stock and thyme, bring to the simmer, then reduce heat to low and simmer until potato is tender (10-20 minutes). Remove potato with a slotted spoon, set aside and keep warm.

2.Bring stock to the boil over high heat, add mussels and stir occasionally until opened (3-5 minutes). Transfer to potato, keep warm.

3.Reduce heat to medium, add fish to stock, poach until just cooked through (3-5 minutes), add parsley and season to taste.

4.Meanwhile, for croûtons, heat clarified butter in a frying pan over medium heat, add bread and cook, turning once, until golden (1-2 minutes each side). Rub bread and serving bowls with garlic clove, then discard garlic. Divide croûtons among bowls, top with potatoes and mussels, then ladle over fish and soup. Season liberally with freshly ground black pepper and serve hot.
